Abstract: A self-injection device (100, 200), including a pen body (108, 208) connectable to a pen needle (10), and a cap (104, 204) selectively connectable to the pen body (108, 208) in a first orientation with respect to the pen body (108, 208) to minimize the length or volume of the self injection device (100, 200), and in a second orientation to provide sufficient length or volume in an interior of the cap (104, 204) to house a pen needle (10) connected to the pen body (108, 208).

Abstract: A tray for positioning elongated objects each having a body and a flange. The tray includes a plate with openings and bearing surfaces. At least one first bearing surface is near a first opening and located at a first distance from the plate of the tray, and at least one second bearing surface is near a second opening adjacent the first opening and located at a second distance from the plate of the tray. The second distance is different from the first distance. The first and second openings are located at a distance with respect to one another such that the flange of a first elongated object engaged in one of these openings is able to partially overlap the flange of a second elongated object engaged in the other of these openings without contact between the flange of the first elongated object and the flange of the second elongated object.

Abstract: A cartridge or injector for holding and mixing a medical product is provided herein including a tubular body having a cylindrical wall having first and second opposing ends. The wall includes inner and outer surfaces with the inner surface having a generally constant cross-section along at least a drug mixing area. A first stopper is slidably disposed within the wall between the first and second ends, the first stopper defining a liquid-tight seal with the inner surface. A second stopper is slidably disposed within the wall between the first stopper and the first end, the second stopper defining a liquid-tight seal with the inner surface. A flexible insert is disposed at or in proximity to the second end, the insert forming a liquid-tight seal with the wall, the insert being pierceable by a medical needle or other piercing instrument. A rigid retainer is fixed to the wall having an opening therein for providing access to the insert for piercing by a medical needle.

Abstract: Each of said elongated objects comprises a body and a flange. The tray includes a plate with openings and bearing surfaces. According to the invention: the tray includes at least one first bearing surface near a first opening, located at a first distance from the plate of the tray, and at least one second bearing surface near a second opening adjacent said first opening located at a second distance from the plate of the tray, said second distance being different from said first distance; said first and second openings are located at a distance one with respect to the other such that the flange of the object engaged in one of these openings is able to partially overlap the flange of the object engaged in the other of these openings without contact with this flange.

Abstract: A scalpel handle includes a sliding shield to block the blade tip or surround the blade when the scalpel is not in use. The shield is advantageously slidable from an extended position to a withdrawn position, wherein the shield is substantially within the handle. Consequently, the user's hand grasps only onto the handle, and not the shield. This helps to provide a more solid feel, similar to a conventional scalpel handle. When in the withdrawn position, the shield avoids interfering with cutting or puncturing blade movements.

Abstract: A disposable scalpel has a blade attached to a handle. The scalpel is weighted, so that although it is disposable, it has a weight similar to the weight of a conventional, nondisposable metal scalpel. The scalpel may be weighted by one or more solid metal slugs within the handle, by particles of weight material within the handle, or by manufacturing the handle including weight materials, such as molded plastics including weighted filler, such as a metal powder. A shield assembly is slidable within the handle from an extended position, where the shield blocks access to the blade, to a retracted position, where the shield is substantially within the handle, and the blade is fully exposed. A locking mechanism locks the shield into the extended and retracted positions.
